A buddy of mine is like
"yo JDM guy JDM" because he claims he has a JDM A20A in his garage. WELL!
I went to see it and it looks the same as my USDM A20A engine.
How can I tell just by looking at it if it is indeed a JDM A20.
ALSO...are there any internal differences known between the JDM and USDM engines?
Tnkx for any info!
